The USB icon device didn't show up. i tried put sd card at cybook, but it doesn't show up either on my laptop. But Show up in my Cybook.

I unplugged it again and tried every single USB port on my laptop ( there 3 USB port), still not work. My laptop doesn't even recognize that the Cybook is there

Those steps are fine, just make sure that:

a) The Cybook is turned ON before you plug it to the computer. It needs to be on for the computer to recognize it as a storage unit.

b) You plug the USB cable completely inside the Cybook. Note that it needs a thinner than usual plug there and, if you don't insert it completely, it can show the "charging" icon but not appear in the computer (it has happened to me).
